Note: This release contains some information about Compiler. your license configuration does include feature, just ignore topics related C++. NOTE: Recompile your sources
List Features
compiler optimizes loops into do.while loops code more compact.This results faster code too. error messages written stdout. With WinEdit `Capture Output' feature Project->Configure dialog used error feedback. other applications Microsoft Visual Developer Studio (MSDEV) cmd.exe command shell, necessary launcher application `piper.exe' direct error feedback. compiler Win32 Window application this type application expected have reasonable output. command shell `cmd.exe' MSDEV stdout file. `piper.exe' tool actually Win32 command line application therefore MSDEV `cmd.exe' stdout. first argument `piper.exe' used application called with remaining options. output started application then written standard output. print list option command window (instead tool compiler/linker/. name).
piper.exe tool.exe
there nameless struct union (e.g. typedef struct _tagStruct };), name written object file better debugging support. Additionally there extended debugging support enumerations, that means following source debug information available enumeration values RED, GREEN, BLUE, WOOD, STONE, IRON MARBLE:
enum Color_tag RED, GREEN, BLUE} Colors; enum Color_tag taged_color; typedef enum Material_tag WOOD, STONE, IRON, MARBLE} Materials; enum Material_tag taged_material; Materials material;
List fixed Bugs
Register trace following pseudo source code example fixed: if(ch val1) ch++; if(ch val2) reloaded conditional change ch++ Accesses indirections volatile memory (e.g. constant pointer deref. like *((volatile char 0x200) were optimized some cases. This fixed cannot happen anymore.

Absolute objects work correctly. compiler adds address twice, accesses absolute object address 0x1000 address 0x2000. absolute objects. Volatile accesses sometimes optimized compiler. compiler cannot handle switch expression over long variables. Workaround: if-else if-else Example: unsigned long unsigned switch(uL) case break; case break; default: break; produces error message, above statement rewritten with if-else if-else: unsigned long unsigned else else messages back error message format (e.g. C1234: ERROR message). options only affect messages message format with proceeding number -OdocF option does care about illegal option combinations (e.g. mixing memory models). careful with aliases: common subexpression elimination (option -Oc) cannot check cases memory location referenced with several pointers, e.g. pointer pointing itself. Incorrect code generated following example: char *p++ workaround: char p++; Preprocessor directive #line implemented, directive ignored.

Release Notes CHC08 environment variable used preprocessor output file name does contain path (NOTE: relative path path too!). compiler exists forms with graphical user interface chc08.exe with command line user interface cchc08.exe cchc08.exe Win32 command line application only true Win32 systems Windows Windows higher, Win32s. command line version compiler does project.ini way. Options must given command line (recommended) COMPOPTIONS entry default.env. Filename surrounded double quotes. Then filenames paths also contain spaces. option generates listing file, which then read assembler. This way, information header file gets accessible assembler modules. With option -lasm compiler itself generates listing file. Note current beta version, assembly output module completely finished still subject changes. option -NoBeep disable beep case error. possible redirect message output file tool started using command shell. Example: 'c:\hiware\prog\linker.exe fibo.prm output.txt'. NOTE: tool launched command shell under Win95, have '/wait' start command shell wait until started application terminates, e.g. 'start /wait c:\hiware\prog\linker.exe fibo.prm'. warning message 'C1805: standard conversion used' object pointer (e.g. pointer struct) assigned function pointer. Previously there error message 'C1806: illegal cast operation' this case. possible check source option active. EBNF grammar OptionActive "_OPTION_ACTIVE_" string ")". used preprocessor code too: _OPTION_ACTIVE_("-W2") option #endif void main(void) (_OPTION_ACTIVE_("-or")) i=2; virtual function management: avoid create virtual table pointer when possible (less virtual tables, less code). option -Lic display license information (note: this information also displayed about box) defines _LITTLE_ENDIAN_ _BIG_ENDIAN_ identify data allocation. manual details. option -Ldf write compiler defined defines file (see manual details). page 6/25
Release Notes CHC08 options -WmsgFoi -WmsgFob specify message format batch interactive format. This options using format string flexible message format. compiler tries integral compares instead double compares whenever possible. This reduces usage runtime libraries increases code speed. option -Ont used switch this optimization off. -Ont option does have suboptions disable single optimizations. libraries STL, "complex", "bitset", "strstream" added. Bitfields inside unions legal Example: struct union char legal options -CswMinLF, -CswMaxLF, -CswMinLB configure switch processor behavior (HI-CROSS+ only), manual details. macro _VERSION_ identify compiler version. E.g. compiler V5.0.2 value macro 5002, compiler with version V3.0.17 3017. Functions containing function calls and/or loops inside inlined, Global variable address modifier Global variables specific addresses with global variable address modifier. following syntax: Declaration <TypeSpec><Declarator>[@ <Address>][=<Initializer>]; Example: glob @0xff02; variable "glob" lies 0xff02 option -ObjN specify object file name, default "-ObjN=%n.o". This option allows changing default object file name which normally source file name with extension ".o". E.g. specify extension ".obj" object files generated compiler, option "-ObjN=%n.obj" specified (see manual details). option -Wmsg8x3 only): This option truncates file names message file MS-DOS format (8.3 format). E.g. this option source file named `mysourcefile.c', source file referenced message output `mysource.c'. This default behavior earlier versions, because some editors (e.g. very versions WinEdit) have problems with file names larger than format. default truncate source file name message output. Local static variables qualified, Example: void static number pragmas active same time longer artificially limited. pragma MESSAGE used messages certain kind. E.g. message `Implicit Function Definition' error.

Release Notes CHC08 pragma OPTION used enable certain options some functions only. E.g. enable -cni during time critical function. Characters with ACSII code larger than 0x7f were treated from previous compiler versions white space characters (like space). This compiler version emits error. Characters with ACSII code larger than 0x7f were treated from previous compiler versions white space characters (like space). This compiler version emits error. pragma STRING_SEG STRING_SECTION allows allocation following strings into specific segment. Strings into named segment handled linker like constants. string segment pragma must also contain modifiers like "SHORT" other segment pragmas strings allocated default way. Example: strings "Print %s", "Print" "str" allocated segment MY_STRINGS.
#pragma STRING_SEG MY_STRINGS void main(void) printf("Print %s", "Print"); char* str="str"; #pragma STRING_SEG DEFAULT
HICROSS +compilers also support directory searching feature environment variables. compiler finds include files included with (#include <test.h>) directory c:\hicross\work subdirectory directory c:\hicross\lib with following entry default.env

Template class with multiple inheritance having base classes generated same template Constructors calling base class Constructors corrected Example: template <class class public: foo(char template <class class public foo<T>, foo2<int> public hoo(char char dir) foo<int>(1), foo<T>(2) hoo<char> P(1,2); Avoid generate virtual function call where necessary. Inline assembly comments could produce error, illegal numbers were written. they skipped correctly parser. messages generated, empty error/message file generated now. Previously there error file compiler issue message. This caused problems with Codewright editor which expects always message file, even there messages. Referencing array-type member struct constant address generates correct code. Example: struct struct char buf[2]; ar[4]; char void main() ch=(char)(&((struct A*)0x00)->ar[1]); Constructor call "new" operator call with array inherited class assigned pointer base class. Example: class A(); class B(); void f(void) B[5]; generating correct Constructor calls Arrays first defined then declared work correctly. With object file format, compiler internal error elf.c module reported. HICROSS object file format, object only declared,

This occur only following cases first definition then declaration (reverse order usual case) only arrays array declared without array size (not form "extern char a8;") Odocf Problem: when starting compiler from command line from maker, -odocf ignored until when double quotes were escaped. E.g. compiler.exe -odocf="-or" never -or. reason that command.com does only forward following compiler: 'compiler.exe odocf=-or' -odocf=-or ignored. this error. Especially makefiles using odocf will work until double quotes were escaped correctly. E.g. compiler.exe -odocf=\"-or\" Indirection address constant variable lvalue Example: const void f(void) *(int *)&i=2; legal Compiler endless loop statement for(;;); fixed. Inconsistency problem interrupt functions (with interrupt keyword) having prototype without interrupt keyword solved (i.e. interrupt function RTI). Parameter passing problem function with more than parameters (one parameter register) solved (stack incorrect) Compiler optimize away inline assembler instruction that made sense. Compiler optimize code compare without branch which incorrect there side effects like assignments function calls. Now, code compares will removed anymore Example: assignment removed char void f(void) if(ch

List Features
option -Wmsg8x3 only): This option truncates file names message file MS-DOS format (8.3 format). E.g. this option source file named `mysourcefile.c', source file referenced message output `mysource.c'. This default behaviour earlier versions, because some editors (e.g. very versions WinEdit) have problems with file names larger than format. default truncate source file name message output. option -ObjN specify object file name, default "-ObjN=%n.o". This option allows changing default object file name which normally source file name with extension ".o". E.g. specify extension ".obj" object files generated compiler, option "-ObjN=%n.obj" specified (see manual details). compiler tries load first variable instead constant byte comparisons. This allows better register usage results denser code. Example: immediate loaded into register variable `ch' loaded option -BfaB (see manual details): Allocation bitfields with size between bits allocate only bytes instead bytes. Example: typedef struct unsigned long b18: sizeof(B) interrupt keyword functional. Example: void interrupt foo(void){} interrupt vector (address 0xFFFE) option specify virtual table delta size (-Tvtd, manual details (option T)). Previously delta value inside virtual tables type 'size_t', possible specify smaller larger) type using option Using virtual member functions, virtual function tables generated. Those tables contain function pointer associated delta value used access base class. Usually those delta values have (signed) 16bit type, allowing class objects with size 32kByte each. save usage such tables, type this delta value changed using -Tvtd option. E.g. class objects smaller equal bytes, then virtual table delta type changed bytes (signed!) type using -Tvtd. there should class object fitting into this type, error message (C1393) will generated. TreeOptimizer (option -Ont switch off) warns about removed labeled statements. Example: switch(i) Label: Labeled statement removed TreeOptimizer (option -Ont switch off) does also optimize modulo operationswith constant unsigned characters.
